Expand and fix auto-generated file filtering in is_valid_file()

[PeterDaveHello]

Split exact generated filenames from suffix matches so lockfiles are matched by basename, while generated assets such as minified files and source maps use suffix matching. Normalize path separators before basename matching so nested paths are handled consistently.

GitHub Copilot PR summary:

This pull request updates the logic in the is_valid_file function to more accurately filter out auto-generated files and certain file types. The main improvement is a more comprehensive and robust check for files that should be ignored, such as lock files and minified or source map files.

File filtering improvements:

• Expanded the list of auto-generated files to ignore by using a set (auto_generated_files_exact) that now includes additional lock files like pnpm-lock.yaml, go.sum, .terraform.lock.hcl, uv.lock, Cargo.lock, Pipfile.lock, mix.lock, pubspec.lock, and bun.lockb. The check now matches the exact filename rather than just suffixes.
• Added a tuple (auto_generated_suffixes) to filter out files ending with .min.js, .min.css, .js.map, .ts.map, and .css.map, ensuring minified and source map files are ignored.

1. pr_agent/algo/language_handler.py ✨ Enhancement +10/-4

Enhanced auto-generated file filtering logic

• Converted lockfile list to set auto_generated_files_exact with 13 lockfile types
• Added auto_generated_suffixes tuple for minified and source map files
• Implemented path separator normalization using replace('\\', '/').split('/')[-1] for basename
 extraction

1. Single quotes in is_valid_file() 📘 Rule violation ⚙ Maintainability

Description

New string literals use single quotes, conflicting with the repo’s Ruff style requirement to prefer
double quotes. This may cause CI/lint failures or inconsistent formatting across the codebase.

Code

pr_agent/algo/language_handler.py[R23-32]

+    auto_generated_files_exact = {
+        'package-lock.json', 'yarn.lock', 'pnpm-lock.yaml', 'composer.lock', 'Gemfile.lock',
+        'poetry.lock', 'go.sum', '.terraform.lock.hcl', 'uv.lock',
+        'Cargo.lock', 'Pipfile.lock', 'mix.lock', 'pubspec.lock', 'bun.lockb',
+    }
+    auto_generated_suffixes = ('.min.js', '.min.css', '.js.map', '.ts.map', '.css.map')
+    if filename.replace('\\', '/').split('/')[-1] in auto_generated_files_exact:
+        return False
+    if filename.endswith(auto_generated_suffixes):
+        return False

Evidence

PR Compliance ID 6 requires Ruff style including double quotes for strings; the added code
introduces multiple single-quoted string literals (e.g., in auto_generated_files_exact,
auto_generated_suffixes, and filename.replace('\\', '/')).

This file already uses single quotes, and the current repo config does not enforce a specific quote style.
